LaserScience: The science of laser projection and light

It was great to see you at LaserScience. So how did we see you, anyway? And what did you see?

Let's play with Light and find out!

Persistance of Vision

Our eyes are slow. They’re good at seeing stuff appear, but not so good at seeing stuff disappear. It takes a moment for bright pictures to fade away in your eyes. So, if you move a light, you see where it is, while you’re also seeing where it was!

Ready to try it yourself?

This is the same software you used at the Paint with Light photobooth. You'll need a computer with a web-cam to use this tool at home.

Grab a flashlight and turn off the lights. Then turn on your webcam and try it out!

If you don't have a web-cam, and you still want to try, e-mail us at to find out where our photo booth will be next!

Lasers

Lasers emit light in one single color. Though he wasn't the first person to make a working laser, the concept of how to acheive this actually came from Albert Einstein's ideas. Twice! First, he suggested that travels in individual packets called photons. Then later he realized that two packets couldn't be in the same place. He suggested that using a mirror to send light emitted by an atom back into itself would cause a chain reaction generating a huge amount of single-colored light. Einstein was right, and this is pretty much how lasers work today!

Color

So far, we've looked at what happens when you have a single color of light. But, what if you use a bunch of different colors?

The light we're used to seeing is actually a mix of colors all together, even if it looks like one color! To learn more about colored light and how our eyes see colors, check our web colors page.
